Yeah according to the thread I link below he was permabanned with all his accounts. For a reason at that. 
Depends. Based on the fact he was permabanned he clearly earned it as even most gankers don’t get such treatment thus easy to see he done something to warrant it, probably many things actually.
So in the end for the sake of the players of EVE and probably his own mental health it is better for everyone involved this way. So if anything it is a cheerful thing instead.
Here’s his thread about it on reddit (not even r/Eve, maybe he was banned from there too I guess, and actually even his reddit account was suspended, I mean really how hard it is to control your emotions and not get banned from everywhere).
Quite a wall of Karen complaint post if you’ve ever seen one, surpassing even most miner rage quit posts.
Also fun fact:
I am EVE Online player Adrian Vexier. I discovered EVE 6 years ago (2017)
He started the same time as I did.
Reading the comments he didn’t get the response he was hoping for. I guess no sympathy for confirmed toxic people. I bet I am not even aware of half of the things he did as I don’t keep track of his stuff just see some of it occasionally pop up and had some interactions with him personally here and there.
I guess what goes around comes around in the end. As one prominent forum member here used to say: good riddance.
Oh and just to commemorate my most impactful encounter with him:
here’s a memorabilia:
